Description
Reference table from the Third Dutch Growth Study 1980
Format
A data frame with seven variables:
- list("pop")
Study Population
- list("sub")
Subpopulation, e.g. ethnicity or age group (for
nl4.wfh)- list("sex")
Sex (M,F)
- list("x")
Decimal age (0-21 years) or Height (for
nl4.wfh)- list("L")
Lambda (skewness) curve
- list("M")
Median curve
- list("S")
Coefficient of Variation curve
Details
The model was fitted by the LMS model. Parameters are stored as type
LMS. Tabulated values are point ages.
Height follows a normal distribution, with all lambda parameters set equal to
1. The standard deviation (in cm) is obtained as S*M.
The naming conventions are as follows:
- list("nl4.hgt")
Length/Height (cm) for Age
- list("nl4.wgt")
Weight (kg) for Age
- list("nl4.wfh")
Weight (kg) for Height (cm)
- list("nl4.bmi")
Head circumference (cm) for Age
- list("nl4.lgl")
Leg Length (cm) for Age
- list("nl4.hip")
Hip circumference (cm) for Age
- list("nl4.wst")
Waist circumference (cm) for Age
- list("nl4.whr")
Waist/Hip ratio for Age
- list("nl4.sit")
Sitting Height for Age
- list("nl4.shh")
Sitting Height/Height ratio for Age
